摘要
针对FROG算法速度较慢的缺点 ,基于对称式数据加密算法的基本原理 ,提出了FROG算法的一种改进方案 ,并对该算法在条件接收系统中的应用进行了探讨 .由于缩短了密钥生成的时间 ,改进后的FROG算法在保持原有可靠性的基础上速度有了显著提高 。
In order to improve the calculating speed of FROG algorithm, some modifications are made based on the principle of symmetric encryption algorithm. It's application in the conditional access system is studied. The experiment results show that the calculating speed of the modified FROG encryption algorithm is faster than that of the old one, while the reliability is remained. So its future application must be prosperous.
